Specification of Letters Patent.

Patented June 11, 1907.

Application led December 3,1906. Serial No. 346,172.

T0 all whom, it 71mg/ concern:

Be it known that we, JOSEPH H. ALLIN and ROBERT L. ALLiN, `citizens ofthe United States, residing at Pecan Gap, in the county of Delta andState of Texas, have invented certain new and useful Improvements inAdjustable Colter-Olamps; and we do declare the following to be a full,clear, and eX- act description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention is an improved adjustable colter clamp, by means of whichthe standard of a colter may be securely fastened to a plow beam of anyconstruction, and may be adjusted as may be desired, and it consists inthe construction, combination, and arrangement of devices hereinafterdescribed and claimed.

In the accompanying drawings,-Figure 1 is partly a side elevationandpartly a longitudinal sectional view of a colter clamp embodying ourimprovements, showing the same in operative relation to the beam of aplow and the standard of a colter; Fig. 2 is a transverse sectional viewof the same; Figs. 3 and 4 are detail perspective views of therespective members of the clamp; Fig. 5 is a perspective view, showingthe outer side of the clamp member 2; and Fig. 6 is a transversesectional view of our improved colter clamp, showing the same inoperative relation to the beam of a plow and the cylindrical standard ofa colter. Fig. 7 is a detail elevation of the wedge block.

Our improved colter clamp comprises two members 1, 2,` adapted to beplaced on opposite sides of a plow beam, such as indicated at a, or ofany other construction, and secured thereto by bolts 3, 4. The. section1, which in practice is a casting, is provided at its upper side with alateral bar 5 to extend above the beam and has at its lower end alateral bar 6 to bear against the lower side of the beam and providedwith a depending ange 7. The bar 5 has a transverse dovetail slot 8which is open at one end, On the outer side of the member l is anoutwardly-projecting portion 9, provided with a vertical slot 10 eX-tending therethrough from its upper to its lower side, said slot beingof such size as to enable it to receive the standard b of a colter andpermit said standard to be disposed either in a vertical position or inan inclined position. In the outer side of the projecting portion 9 atthe center thereof, is a screw-threaded opening 11, in which is aset-screw 12 to bear against the other side of the standard l) and clampthe same in place. In the front and rear sides of the said projectingportion 9 are similar openings 13 to receive screws 14, the said screwsbearing against the front and rear edges of the colter and serving inconnection with the screw 12 to securely hold the colter either in avertical or in a forwardly or rparwardly inclined position at anydesired ang e.

The section 2 has at its upper end a laterally-extending bar 15 toextend above the plow beam and has at its lower end a bar 16 to bearagainst the lower side of the plow beam and provided with a flange 17.The bolts l are placed in openings in the flanges 7 and 17, and thebolts 3 are placed in openings at the upper ends of the member 1, 2,said bolts 3, 4, as hereinbefore stated, serving to clamp said membersto opposite sides of the plow beam. The bar 15 of the clamp member 2 hason its upper side a dovetail shoulder 18 to enter and it in the dovetailslot 8 of the bar 5 of the member l. It will be understood from theinspection of Fig. 2 of the drawings, that the upper lateral bars of therespective members 1, 2, are disposed in overlapped relation above theplow beam and that the said members may be moved toward and from eachother to narrow or widen the space between them and hence said membersof the clamp may be firmly bolted on a plow beam of any constructionwhether of wood, iron, or steel, and of any size.

We also employ a wedge block 19, which is inserted between the upperedge of the plow beam and the lateral bar 15 of the clamp member 2, tofill the space between the beam and said bar and adapt the clamp to beattached to beams which vary in width vertically. The said wedge blockhas a series of depressions or seats 2O in the upper side for thereception of the lower end of a setscrew 21, which operates in athreaded opening in the bar 15 of the member 2. On the under side of thesaid wedge block are transverse, serrations 22 to engage the upper sideof the beam and insure a firm grip between the wedge block and the beam.

To enable the clamp to be employed to secure a colter having acylindrical standard c to the beam, we providethe clamp member 2 with anoutwardly-extending, vertically-disposed portion 23 on its outer side,provided with a vertical, cylindrical slot 24 IOO IIO

extending therethrough from its upper to its lower side, and of asuitable size to receive said standard c. Said portion 23 is providedwith set-screws 25 to clamp the said standard.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention, as deiined by theappended claims.

Having thus described our invention, what we claim as new, and desire tosecure by Letters-Patent, is-,

1, A colter clamp of the class described comprising a pair of members toengage opposite sides of a beam and provided with overlapping bars, oneof said 'bars having a transverse slot and the other having a transverseshoulder to engage said slot, means to adj ustably secure said memberstogether and clamp them on opposite sides of the beam, one of saidmembers having means, independent of the said securing and clampingmeans, to adjustably secure a colter standard to said member.

2. A colter clamp of the class described comprising a pair of members toengage opposite sides of a beam, one of said members having a verticalopening to receive the standard of a colter, and further provided withmeans to receive said standard at any desired adjustment, and meansindependent of said standard receiving means, to clamp the said memberson opposite sides of the beam.

In testimony whereof we have hereunto set our hand in presence of twosubscribing witnesses.
